Certonotus Kriechbaumer (Hymenoptera: Ichneumonidae), an Australian Genus Newly Recorded in South America

Porter, Charles C.

Abstract

Certonotus is cited for the 1st time from temperate South America. The genus formerly was believed to be endemic to the Australian zoogeographical region and to some nearby islands. Certonotus invictus n. sp. and C. umbrarum n. sp. inhabit moist, cool Nothofagus woods of south Chile and adjacent Argentina. These species differ in many characters but may be distinguished most easily because C. invictus has slender, largely fulvous legs, while the legs of C. umbrarum are black with white markings and much more robust.
